From c6ea696f73f47259543ae1526f99ec075cbb4333 Mon Sep 17 00:00:00 2001 From: LABBE Corentin Date: Wed, 31 May 2017 09:18:46 +0200 Subject: [PATCH] arm64: allwinner: sun50i-a64: add dwmac-sun8i Ethernet driver The dwmac-sun8i is an Ethernet MAC that supports 10/100/1000 Mbit connections. It is very similar to the device found in the Allwinner H3, but lacks the internal 100 Mbit PHY and its associated control bits. This adds the necessary bits to the Allwinner A64 SoC .dtsi, but keeps it disabled at this level. Signed-off-by: Corentin Labbe Signed-off-by: David S.
